STEAM-REGENERATIVE ACCUMULATOR.

Application filed September 27, 1911.

To all whom it may concern:

Be it known that I, LnoNon P. L. BATTU, a citizen of the United States,residing in New York city, county and State of New York, have inventedcertain new and useful Improvements in Steam-Regenerative Accumulators,of which the following is a full, clear, concise, and exact description,reference being made to the accompanying drawing, forming a part of thisspecification.

My invention has for an object the regulation of a variable fluX ofsteam and by means of it an intermittent flux of steam can be convertedinto a practically regular flux of steam.

My invention is especially well adapted to regulate the exhaust steam ofintermittent high pressure engines for the purpose of driving continuousrunning low pressure e11- gines. I interpose between the source of intermittent steam and the point where this intermittent steam is utilizeda vessel having a volumetric and thermic storage capacity. Thevolumetric storage capacity for steam is due to the expansion of thevessel interposed between the source of intermittent steam and its pointof use. The thermic storage capacity is due to the increase oftemperature of water contained in the expanding vessel subsequent toincrease of steam pressure in said vessel. It will be seen from thedetailed description that the pressure within the vessel is obliged torise and fall in a very special manner. The water contained within thevessel will be subjected to various steam pressures and will thereforebe capable of absorbing and giving off heat.

I will explain my invention more fully by reference to the accompanyingdrawing, showing one application and embodiment of the invention, inwhich A is a high pressure engine whose flux of steam is to be regulatedby my apparatus.

B is a low pressure engine which receives from my apparatus a continuousflux of steam.

C is a pipe line leading steam from high pressure engine A andcommunicates by means of pipe E with my regulating apparatus. It will beseen that pipe E is adapted to allow steam to flow to and from theregenerator. Steam also passes through pipes E and D on its way .to thelow p ps? Specification of Letters Patent.

sure engine B, the pipe E being used for incoming and outgoing steam.

F is an inverted bell whose lower end is open and submerged in the wellG, which is filled with water to the level H. As shown in the drawing,water level H has been displaced by pressure in the vessel to a lowerposition, H

1 is a conical cap placed over the top of plpe E, by means of whichwater is prevented from falling into pipe E.

J is a cylinder affixed to bell F.

K is a piston aflixed to pipe E and moving within cylinder J,constituting a dashpot, which prevents violent up and down movements ofthe inverted bell F.

L and L are diaphragms affixed to inverted bell F, occupying a positionalways beneath the water level and by their motion cause a thoroughmixing of the water within the well G.

M and M are annular trays affixed to the upper portion of bell F and areprovided with a large number of small holes N.

O and O are flap valves placed on the bottom of thetrays M andM whichopen to admit water freely to the trays, but close to prevent waterflowing outward from the trays.

P is a valve located in the upper portion of bell F and is opened by arising action of the bell F. Valve P begins to open when its upperportion is pressed sufiiciently against the horizontal bar Q, which isaffixed to the columns R and R Uoil spring P reacts against the pressureagainst the bar (.2 and has a closing action upon valve P.

S and S are counterweights, which eXert a lifting action on bell F bymeans of cables T and T U is a safety valve opening upward and heldagainst the pressure of atmosphere by the adjustable compression springV.

The operation of my apparatus is a follows: Steam enters the invertedbell F through piping O and E, raising the pressure within the bell Fand lifting it out of the water. The trays M and M are submerged beneaththe water level when the bell F occupies its lower position and thesteam must have a sufficient pressure to elevate inverted bell F,together with the water contents of the trays M and M a fu rthe rincrease in pressure causing the inverted bell F to rise to higher andhigher positions. The water contained in trays M and M pours outwardvand downward through the perforations 'N, constituting a large number ofsmall streams of water passing through the steam contained within bell Fandcondensing large amounts of steam, absorbing the heat and raising thetemperature of the Waterto the temperature of the steam Within the bellF. WVhen the steam stored Within the bell F, due ,to displacement anddue to the absorption by the water from the trays M and M has reachedits'maximum value, the, bell F is at its greatest height andanyadditio'nalsteam entering willcause an opening of valve P, allowingthe surplus steam to be discharged to atmosphere. V

- During the operation of absorption of steam by the bel'lF, the lowpressure engine B is withdrawingsteam through piping E and D, and thesteam'referred to above as .being absorbed by displacement ofbell F andbythe heating of water contained by trays M and M is the excess of steamdelivered by engine A over that requiredby engine B. Adeficiency ofsteam for theoperation of engine B will cause more steam to leave thebell F than enters and this steam will be supplied bythe evaporationotwater previously heated during a period of excess steamand also by thedisplacement of steam arising from the descent ofbell F. The diaphragmsL and L in moving up and down through the water give an activeCirculation to the water, which,,..permits it to vary in temperature bythe absorption and delivery of steam as thepressures changewithin thebell F. The dashpot J and piston K act to steady the vertical movementsof inverted bell F and prevent too viole'nt oscillations. The safetyvalve U is ,.-provided in order to avoid the possibility of the pressurewithin the bell F falling under an unsafe limit and the spring V is soadjusted that the pressure of atmosphere will open valve when thediflerence in: pressure between atmosphere and the pressure within thebell F has reached the maximum permissible value.

. When the trays M and M are. immersed in the water, the effortnecessary to lift bell F is less than when the trays filled with waterare above the level. of the Water contained in well or vessel G.- Inorder. that the pressure of the steam shouldlift these trays it isnecessary that the pressure of the steam. should increase. This riseinjsteam pressure creates a rise in. temperature and gives to theregenerator, ion accountof the presence of the water, a thermic storagecav pacity. If the bell F wasnot equipped with trays and if its weightdid notmaterially increase when the steam raisesthe bell out of the.water, the pressure of the steam would have a marked tendency to remainpractically constant and the action of the x perature' corresponding tothe temperature of thesteam it could not absorb any more heat andtherefore could not condense the excess steam.

' Having thus described my invention, I claim as new and desire tosecure by Letters Patent:
